Agree with everything you say Moneyseeker, an F1 race meeting has to be a greater event than just the race if it is to attract enough spectators. In this day and age one sees more of the race on TV than at the circuit where only a few hundred yards are ever in view. For me F! Is interesting rather than exciting, I only attend the British and even then watch mainly on a TV screen.
As a circuit Silverstone is fantastic, fast, complex, a real test of car and driver but for viewing not a patch on Brands Indie!
So I fear we shall lose the spectacle of those fast sweeps taken by an F1 car, lose the essence of F1 that is really pricing itself out of market.. A race round the docklands can never be the same but would probably win on accessibility
